Who needs a new skin the most?

A lot of the champions in the game seem to be really fall behind in decent skin count, while some champions seem to get a new skin every other week (Annie, Kog'maw, Teemo, etc). Who do you think really needs a new skin the most?
My money's on Urgot. He's far too awesome to have only two skins.

We are gunna use some dust brown to paint some happy little tornados here, and one more here. Then we are going to use some white to paint happy little wind blasts here. Just dab the brush along the base of al akir, and there you have it. THE GAYEST FIGHT EVER

Some of them are obviously to young to get a new skin in the nearer future. But especially Janna, Soraka and Udyr are there since '09 and more or less often played so they could use some love. Swain and Urgot are quite old, too.
Brand isn't on the list anymore because his new skin was released yesterday/today. (even if he is from '11)

Not on this list but I would literally die to get a Blood Moon Kennen! >.< Even if it's a super legendary skin for 5k RP I would buy it in an instant.

Trundle and Rumble are in dire need of new skins. I'd love to see a MechAssault or Mech Warrior skin for Rumble, and perhaps a pre-cursed Trundle? There are skins like that such as Human Ryze, pre-void Kassadin, and I think there is one more

While Enemy Crabgot is awesome beyond belief, I still feel like he's missing something. Maybe a Gentleman Urgot skin? A nasty looking mechanical monster in a tux with a monacle over his one good eye (I think it's good... looks kinda nasty) who fires shrimp forks out of his arm instead of glaives would be really friggen epic. Urgot, Gragas and Cho'gath could start a gentlemen's club together.

On a side note, they need to have some sort of epic event where Urgot faces off against Garen for vengeance.
